v1.2.0

This release mainly fixes the compatibility with dissect.cstruct v4 and drops support for EOL Python versions going forward, the minimal requirement is now Python 3.9.

Python packages are now also automatically uploaded to pypi.org, including the dev packages from the main branch.

$ pip install --pre dissect.cobaltstrike
